Later .......PC Dr. sort of fixed the problem, at least stopped Delta Search from opening instead of Chrome, but was a but vague as to what he had done, re-set the pages I think he said, but I'm not sure that it has been completely removed, it still shows as an option in the list of available browsers, along with all the others that I don't need, or use.
However, in view of Milos' advice I've switched to Firefox, tho' I haven't attempted all the other steps suggested yet.
Thank you for all the advice, it has been filed for possible later use.
